Shoeprint Alignment for Feature Extraction

Shoeprint Alignment for Feature Extraction

Image Database

Main Objective

To develop an automatic algorithm to match two scans corresponding to the same shoe based on analysis of cross-section

In order to do this we need:

  1. Align images so we can identify the same cross-sections on all the shoes
  2. Identify the areas with the most potential for discrimination
  3. Extract cross-section signatures in such areas
  4. Study the correlationn of cross-section on both match and non-match pairs
  5. Use the cross-section signatures to construct informative features
  6. Fit and asses statistical models
